asteroid set to fly by earth

Maybe it was the moment he first looked into her head, and saw the fear of losing everything. In a moment where his mind was open-seeing what all of the paladins of Voltron thought and felt-and recognizing her fear of losing the only hope she had left; that her brother and father were alive somewhere.

Maybe it was when she didn’t hesitate to insult Allura. When she wasn’t afraid to stand up for herself and make it known that she wasn’t going to be taken advantage of or broken down.

“Oh, the princess of what?”

15 000 space rocks and counting

The international effort to find, confirm and catalogue the multitude of asteroids that pose a threat to our planet has reached a milestone: 15 000 discovered – with many more to go.

The number of catalogued asteroids approaching Earth has grown rapidly since the count reached 10 000 only three years ago.

Near-Earth objects, or NEOs, are asteroids or comets with sizes ranging from metres to tens of kilometres whose orbits come close to ours, meaning they could hit our planet.

The discovered NEOs are part of a much larger population of more than 700 000 known asteroids in our Solar System.

“The rate of discovery has been high in the past few years, and teams worldwide have been discovering on average 30 new ones per week,” says Ettore Perozzi, manager of the NEO Coordination Centre at ESA’s centre near Rome, Italy.

“A few decades back, 30 were found in a typical year, so international efforts are starting to pay off. We believe that 90% of objects larger than 1000 m have been discovered, but – even with the recent milestone – we’ve only found just 10% of the 100 m NEOs and less than 1% of the 40 m ones.”

Today, the two main discovery efforts are in the US: the Catalina Sky Survey in Arizona, and the Pan-STARRS project in Hawaii, jointly accounting for about 90% of the new bodies found.

ESA is contributing through its Space Situational Awareness programme, setting up the centre in Italy to combine new and existing European telescope data and support a new network to distribute information.

Maintaining the European risk list
“The centre maintains the European Risk List, containing all objects for which an Earth-impact probability cannot yet be ruled out, however low,” says Detlef Koschny, heading the NEO element of the Space Situational Awareness office.

“There is only a tiny impact probability for any known object in the next 40 years, but all NEOs bear close watching to refine and understand their orbits.”

The coordination centre is also the focal point for scientific studies needed to improve warning services and provide near-realtime data to scientific bodies, international organisations and government decision-makers.

In recent years, astronomers working with or sponsored by ESA have concentrated on follow-up observations, confirming new objects and obtaining more reliable orbits. Some of this work was done with ESA’s own observatory on Tenerife in the Canary Islands.

Others have been instrumental in imaging or confirming the orbits of particularly interesting objects, such as asteroid 2016 RB1, which grazed our planet on 7 September 2016 by 34 000 km, within the orbit of many telecom satellites.

In the coming years, the pace of discovery is likely to increase.
ESA is developing new ‘fly eye’ telescopes to conduct automated nightly wide-sky surveys with their very large fields of view. These are expected to begin operating around 2018. The Large Synoptic Survey Telescope, being built in Chile, is set to begin hunting space rocks in the near future.

These future telescopes offer the almost complete sky coverage and depth needed for humanity to be sure that as many NEOs as possible are discovered and identified before posing any threat.

NASA prepares Orion capsule for debut deep-space test flight

A NASA spacecraft designed to one day fly astronauts to Mars rolled out of its processing hangar at the U.S. space agency’s Kennedy Space Center in Florida on Thursday to be prepared for a debut test flight in December.

“This is a pretty historic moment for us,” Scott Wilson, NASA’s Orion production operations manager, told reporters as workers prepared to move the capsule to a fueling depot. “This marks the end of the assembly process for the spacecraft.”

An unmanned version of the gumdrop-shaped Orion capsule, which has been under construction for three years, is due to launch aboard a United Launch Alliance Delta 4 Heavy rocket on Dec. 4 from nearby Cape Canaveral Air Force Station.

United Launch Alliance is jointly owned by Lockheed Martin Corp and Boeing Co .

In December Orion will be flown to an altitude of about 3,600 miles (5,800 km) from Earth, 14 times farther away than the International Space Station.

The capsule will then careen back toward the planet, slamming into the atmosphere at 20,000 mph (32,000 kph). At that speed, Orion’s thermal protection system should heat up to about 4,000 degrees Fahrenheit (2,200 degrees Celsius), proving the shield can protect astronauts returning from the moon and other deep-space destinations.

Orion is part of NASA’s follow-up program to the now-retired space shuttles that will allow astronauts to travel beyond the International Space Station, which flies about 260 miles (418 km) above Earth.

A test flight with crew aboard is set for 2021. NASA intends to use the rocket and Orion to fly astronauts to an asteroid that has been robotically relocated into a high orbit around the moon. Eventually, the U.S. space agency wants to fly a four-member crew to Mars.

NASA has been out of the human space launch business since the shuttle program ended in 2011.

The agency currently buys rides for space station crew members aboard Russian Soyuz capsules. A heated three-way competition to build a U.S.-based commercial space taxi is also under way. The contenders are privately owned Space Exploration Technologies, also known as SpaceX, privately owned Sierra Nevada Corp and Boeing.

Work on the Orion deep-space capsule, built by Lockheed Martin, began more than a decade ago under NASA’s defunct Constellation moon program. NASA has already spent about $9 billion developing Orion.
